Application filed July 13, 1920, Serial No. 395,950. Renewed May 27, 1924.

To all cc/iom 2'15 may concern:

Be it known that LIVADE WINEMAN, citizen of the United States, residing at Michigan City, in the county of Laporte and State of Indiana, have invented certain new and useful Improvements in Gauging Devices, of which the following is a full, clear, and exact specification. My invention relates to gauging devices, and more particularly to gauging devices for imparting a proper gauge and taper to the forward end of a drill bit or'similar tool.

An" object of my invention is to provide an improved gauging device for tool sharpening mechanisms. A further object of my invention is to provide an improved gauging device which will provide accurate step by step adjustment, of the dies and permit locking of the samein each position. A

still further object of -my invention is to provide, for use withgauging dies, an improved adjusting means for one of said dies comprising a member serving either as a handle for adjustment or as a lock for said parts. Other objects ofmy invention will appear during thecourse of thefollowing specification. i r

In the accompanying drawings I+have shown, for purposes of illustration, one embodiment which my invention may assume in practice.

In these drawings,

Fig. 5 is a plan view of the lower die.

In drilling rock it is a well known fact that during the progress of drilling a hole, the bore of the hole progressively decreases in size, this being due to the fact that the lateral edges of a drill bit and the side surface of the forward end thereof wear away comparatively rapidlydue to their friction on the rock, and accordingly, at the frequent changes of steels which are necessary, it is requisite that a steel having a bit of slightly smaller gauge than that last used be substituted for the drill which it is replacing. It is of course desirable, particularly in drilling a deep hole, to make the changes of gauge as small as possible, for the amount of material that has to be drilled out increases very rapidly as the diameter of the hole increases. I have found in practice that it is highly desirable to form drill bits with a double'taper so'formed as to provide reaming edges, i. e., with an initial taper from the shank of say 12 or 14 degrees and a final taper adjacent the cutting edges of 5 or 7 degrees and with the peripheral surface of the forward end of the bit so formed as to bring the edgesof the wingsinto a cylin drical surface. There is thereby provided a bit having high wear resisting properties and, owing tothe formation of the peripheral wing surface adjacent the cutting edges, one which reduces to a minimum the changes in gauge at the time of changing steels. I have also found that reaming edges formed on a drill bit of the Well known double are double taper type produce a bit of very high efficiency. For the purpose of providing a very simple, rugged and readily operated means for effecting accurate gauging, the formation of a double taper and of a reaming edge, I have devised the mechanism which comprises the subject matter of the present application. In the illustrative embodiment herein disclosed, the lower jawof a vise mechanism which is adapted to clamp a drill steel for the purpose of holding it during dollying operation is indicated at 1. The upper jaw ofthe vise is indicated at 2 and lodged in the two are a pair of dies 3 and 4 for the purpose of holding the drill during the operation mentioned. In the present device I secure to the lower jaw 1 a stationary lower die member 10 provided with a pin 11 seated in asocket 12 formed in the lower jaw, said pin constituting dieholdingmeans. The rear face 13 of the lower die block seats against the forward face 14 of the lower vise jaw and in cooperation with the pin 11 and socket 12 furnishes a rigid mounting for the lower die block. As is well known, the jaw 2 of the vise is readily reciprocable under suitable manual control and I have secured to this upper jaw a movable die 15 to cooperate with the stationary die 10. Rigidly bolted to the front face of the upper vise jaw and having a tenon 16 adapted to fit a mortise 17 formed in the front face of the aw is a die carry ng block 20 which is provided with an upwardly directed tubular portion 21 and with a lower reduced bore '22 it 27 secured in the block 20 and having a spring 28 between a second washer 26 adjacent the head ofthe screw 27 and the first mentioned washer 26 to press the latter, and accordingly the pin 24, inwardly. For the 3 purpose of adjusting the die 15 I have threaded the interior of the upper end of the member 21 as indicated at 30 and have mounted a large square-headed follower screw 31 therein, the threads of the screw 31 being relatively coarse to permit endurance of the shock of the blows imparted by the upper jaw 2. Cooperating with the squared head 32 of thefollower screw 31 is a combined handle and locking member 33 having a socket 34 therein fitting the squared head 32 and a lug35 projecting laterally and provided with a pin 36 at right angles thereto, The upper end of the member 21 is provided with an annular flange 37 and in the flange areformed two notches 38 and 39 separated by an angle of 135 degrees, these notches being adapted to receive the handle pin 36 and hold the follower screw 31 against turning.

I have found in practice that a gauge variation of one-thirty-second of an inch or multiple thereof will be sufficient for most purposes and accordingly Ihave provided a screw connection between the follower screw and the top of the member 21 of four threads per inch. Noting the position of the handle 36 in Figs. 2 and 3, and assuming that it be desired to decrease the gauge by one-thirty-second of an inch, the procedure will be as follows: The member 33 will be lifted vertically off the top of the squared member 32 of the follower screw 31. It will then be turned over about a horizontal axis in such manner that the handle 36 projects in the opposite directionandabout a vertical axis in such manner that the handle 36 is diametrically opposite its original position with respect to the follower screw 31. The member 33 will then be again fitted to the projecting stub 32 and turned through an angle of degrees clockwise in Fig. 3. The member 33 will then be removed and inverted about a horizontal axis and the pin 36 inserted in the groove 39 and member 33 fitted to the squared stub 32. The result of this manipulation will be the turning of the follower screw 31 through an angle of 45 degreesor one-eighth of one revolution and accordingly the upper die 15 will be lowered one-eighth multiplied by one-fourth or onethirty-second of an inch.

From the foregoing description the mode of adjustment of the dies will be readily apparent, it being obvious that to effect increase in gauge the direction of rotation of the follower screwiwill be reversed and that the firstvblow upon the steel will cause the die 15 to slip upwardly to its proper position where it will be held by the friction between the pin 24 and the groove 24. It will be noted that the lower die block 10 is provided with a depression in itsupper surface which is tapered angularly at its forward end and deeper at its forward end than adj acent the rear, this surface being adapted to receive and impart to one wing of a drill bit the proper taper, contour and gauge. The uppper die 15 is provided with a ganging surface 42 which is formed with a suitable mean radiusfor the average drill bit which will be formed therein and the upper gauging surface 42 and the lower gauging surface 41 have the same relative angle to a horizontal line and accordingly will gauge a bit inserted between them accurately while at the same time imparting a change of taper to the forward end as may be necessary. If it were desired to use a coarse thread on the screw 31 and to decrease the gauge changes, it would obviously be possible to increase the number of sides on the member 34 while still retaining it of regular polygonal shape, and then place the notches 3S and 39 apart an odd multiple of onehalf the anglesubtended by each side of the polygon. The minimum change in gauge would be then equal to threads per inch angle subtended by each side of polygon From the foregoing description it will be obvious that I have provided an improved simple and eflicient gauging mechanism comprising fixed and movable dies, which is readily adjustable and positively locked in position when adjusted.

While I have in this application specifically described one form which my invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
